Error when updating survey text or options


When trying to update an existing survey, either by changing the survey question, the options to choose or anything at all, the following error is displayed:
A critical error has occurred. Parameter count does not match Parameter Value count.
If you remove an item from the answers of a a question, this works (but error still occurs). Adding items, changing the text of the question etc doesn't work. Versions tested: 4.70.00 and 4.70.01.
